of 0hio, Vhave invented certain new and use `ful Improvementsin Rim and Tire (1on- 'structions for vVehicle W'heels, of which the' following is a speeiliction.

My invention relates to an improvement in rim and' tire constructions for -vcllicle Wheels, and it consists in the 'ombi'nutions, eonstructions and arrangements herein described and claimed. Y

An object ofthe invention is to provide a rinnand. tire constructionv in which thetire. is permitted to have ragliulilexure inward in Athe rimuand is held againstY any nppreciable later-al expansion in responseto pressure on the trend ofthe-tire, whereby a tire having a given :1inJ capacity will be ca- Pble of sustaining a relatively great load without rupture or istortion.

.A further object f.the inventionis the provision. of e rim and -ti-re constructifm which is adapted to beV conveniently :rndeasily applied Vto the felloe of a wheel.

A still further object of the invention is' the provision of a, `rim and tire construetion which is adapted tof-be manufactured' atfa. relatively, low cost and which is.

The tread mem er 14 may be made of any suitable material may have reinforcing wires imbe ded therein as indicated at 15, such' reinforcing wires picferabl bein l ted inthe side members of the bo y oft e casing 14 .adjacent to and in encircling relation to the inner. edges of said side members. f Y e From the foregoing description of the vn rious parts of the device, the o eration there'V y of may be readily understoo The tube-1()n is placed on the outerrimi-m'ember 1 whileV in deflated condition-.fandthe tread member 14 is placed i encirclingrelation to the lperipheral portion Abfvthe tube with t e A the jshoulders 12. `The radial wdt 4of th portionof the tube 10 that is received between the anges 2 of theouter rlm member is at least half the radial distance between'th'e outer and i inner peripheral 4,walls of the --tube 10 Vand lappreciable change the ribsfo'rbeads 411 are' suliienftly stii to support the casing member 14 when the inner tube hasbeen inatedrso that the in' ner edge portions of the sides of the casing member 14' will be held between the-outer edge portions of the flanlsl 2 of, the outer rim member and the exten g 'outer peripheral .portion of, the tube 10A without, any in the cross sectional l contour of the innerwall of the tube 10 ,when

the ,rim anges2 of the the casing member 14 is subjected to shocks 'snhr jars-on the outer periphery thereof." -limited Aradial movement inwardbetweenI casing member 14 is p'crmittedto have!l l Y outerl rim member in response to shocks/and jars on the outer pripheral wall or Ytread 'of the casing mem 14, the body Yof the tube 10 of coursebe made of flexible ensue material andthe .tion ofthe inner vtube 10 being expose to likewlse having wear. The casing member 14 can be replaced at but relatively little cost and the expense incident to thedzreeping of a rim -is annular inform and is adapted'to sides of the casiniM iii-abutting nouer? and tire.construction embod ing the im vention in repair and in con i-tion for use is relativl low. r

The moification shown in'Figure 2 includes an outer. rim member 1a which may be'secure'd in an f suitable known manner alfelly -4 an opposite edges with .outwardly extending whibh is provided at itsI vintegral rim flanges, 2 having outwardly f l and rearwardly curved marginal c dgc portions' The 'rim flanges 2 are shown as bef ing substantially parallel to each other from their 1* to the edge portions 3 and as being yro- .vided 'with fnciug'or cushion members 20 which'mn' be made of solid rubber or rubberized fa ric. The facing membersQO are secured to the inner'faces of the rim fianges 2 in any 'suitable known manner andere mergedV ne into the other byan annular connecting strip 20V which cooperates with the inner ends ofthe members 20 to cover the outer 4face of the bod pf the outer 'ilzuV 1. The out'e'r diameter o 'each of the inembers 20 is less than that of each of the rim ilanges 2 so that each member 20 terminates at its outeredgeshort of the outwardly and rearwardly curved outer ed e of the rim member 2n to whichlit is secure The outer edge of each of thefacing members 20 is concentric with the body of the rim member. 1 and provides va shoulder as indicated at l21. An inner and pneumatic tube 22 which may b e of any suitable or preferred type ofconstruction 1s artially received be- 4tween the facing mem ers 20 and has the inner peripheral wall thereof in abutting relation to the connectin strip 20'. The inner tube 22 thus will e spaced from the outer rim member 1' and its rim flanges by a resilient elastic cushion.

A tread member 14 which may be identical i endg-ier edgesthe shoulders 21 and the tread member 14 thus is supported to have limited iradial movement inward between the rim flan es 2* but will beheld against accidental di p acement by the outer edge ortions of tir rim members2 when the tu 22 is iniated.

Qbvicusl'y, my invention is susceptible of embodiment-in vforms other than those illusgrated in the accompanying drawings and therefore consider as my own al odifications and adaptations of the forms the device herein described as fairly. fall within the scope'ofythe appended claims.
